2) Verb: Also Navy slang to dispose of anything, including figuratively (e.g. ideas, positions, persons, etc.).
Remark: Closely related to (Navy slang) "
chit can", the expression for "shit can" when
vulgarity might constitute a risk, z.B. in the presence of senior commissioned officers, a "chit" being any kind of form,
stub, written request or permission, etc.
1) Don't throw lit butts in the shit can, you fucking idiot !
2) They
shitcanned him in a hurry after he pissed drunk in
